Knowledge about language and its relation to communication skills (or competency) development has been a current topic of L1 didactics not only in the Czech Republic for decades. How much and what kind of knowledge about language do our pupils need? And how does this knowledge align with the development of communication skills? The paper analyses the phenomenon described above in both the historical and contemporary perspective focusing specifically on the situation in the Czech Republic, but also putting the issue in a broader international context.
